Ali Darwish
Ali Darwish is an associate professor and chair of the electronics engineering department at The American University in Cairo.
Professor Ali Darwish received his BS and MS degrees in
electrical engineering, with honors from the University of Maryland, College Park in
1990 and 1992, respectively. He was awarded the National Science
Foundation (NSF) fellowship. He received his Ph.D. degree from the
Massachusetts Institute of Technology, Cambridge, MA, in 1996.
In
1990 he joined COMSAT Labs where he conducted the experimental work for
his M.S. thesis. In 1992 he served as a research assistant in the
optics and quantum electronics group at MIT. In 1997 he co-founded
Amcom Communications, Inc. a leading supplier of high power microwave
devices. In May 2003 he joined a US government research lab where he
conducted research on wide bandgap materials (GaN), thermal analysis of
active devices, and novel MMIC concepts. In Sept. 2006, he joined
University of Sharjah as a visiting faculty member. In Sept. 2007, he
joined the American University of Cairo as a full time faculty member.
He received a promotion to Associate Professor in September 2009.
Darwish is an inventor and the author of 60 technical journal and
conference papers. He served on the Electronics Coordinating
Group (ECOG) of the Army Research Office (ARO), a prestigious board of
top army and university scientists that sets the research priorities
and recommended funding for the defense labs, funding institutions, and
research initiatives. He also drafted several winning proposals on new
product ideas. He won and directed a 4-year $1 million dollar Small
Business Initiative Research (SBIR) grant on three-dimensional
microwave circuits (MMIC and Hybrid). He won grants from AUC, and the
European Union, Research and Development Initiative (RDI) to develop
characterization tools for building materials.
Research Interests:
• New Product Development (NPD).
